Nukeproof Horizon Pro Rear Wheel 148mm Boost

Nukeproof have a proud history in creating high performance hubs and wheels, from the legendary carbon shelled Atom Bomb Hubs in the 1990’s through to more recent Generator, Neutron and Horizon wheelsets. Launched in 2020, the Horizon V2 wheelsets have elevated Nukeproof wheels to the next level of performance. The V2 has been thoroughly tested at the highest level at both the Enduro and Downhill World Cup with the Nukeproof-SRAM Factory team and become a huge favourite with privateers. This has been thanks to the strength, reliability and serviceability of the wheels. But here at Nukeproof we are always looking for the next step in performance. Welcome to the Horizon PRO

Designed as an all-new wheel set created for riders who are looking for the ultimate alloy trail wheel. Using the Horizon V2 as a base, our designers took a fine-tooth comb to the Horizon V2 to make a number of incremental improvements. The main aim of the PRO was to create a lighter wheelset for trail and enduro riders. The result is a ground up design featuring an all-new front and rear wheel. The PRO wheels are lighter, more compliant and using an all-new high performance ratchet engagement hub for the rear wheel. In raw terms, the Horizon PRO offers riders a 9-10% (depending on wheel size combination) weight reduction over our Horizon V2 wheels sets. This makes the Horizon PRO the perfect wheel set for Trail and Enduro riders who are looking for are looking for the ultimate alloy wheelset. ### New Nukeproof Horizon Pro Hub: At the heart of the Horizon PRO is an all-new hub housing a 54T engagement ratchet mechanism. Why move to a ratchet? Because the compact dimensions of the ratchet system allow for reduction and optimisation of the overall hub dimension. Thus, saving weight and offering a rapid and smooth engagement and lost energy through drag in the hub. To further reduce the overall dimensions of the hub, double butted straight pull spokes (2.0mm-1.8mm-2.0mm) are used. These spokes allow further optimising of the hub shell dimensions by machining any unrequired material. With the ratchet system, engagement of each tooth is simultaneous, distributing the force across a larger surface area evenly. This reduces wear and ensures reliability. The result is a sleek shell looks sunning and hugs the new internals but is strong and reliable. The rear hub is fully serviceable with all spares available. ### Freehub driver options: SRAM XD Shimano HG Shimano Microspline ### Hand-Built and Tensioned: To further reduce weight, thanks to the increased tension and strength by using straight pull spokes (vs a J-Bend), the overall spoke count can be reduced to 28. Available in 12x148mm Boost only. Each Horizon PRO is laced by hand in a 3x spoke pattern. The Horizon PRO rim is made from dynamically aged Magnesium-silicon enriched alloy blend. This alloy produces the stiffness and hardness like 7-series, but with the ductility and yield properties of a 6-series alloy. Each rim is sleeved to join to ensure a strong and consistent level of strength around the rim. Overall, this gives means the Horizon PRO offers an incredible blend of stiffness, compliance, strength, and weight. To support spare parts for riders, the front and rear wheels share the same rim and straight pull spoke design. Each rim has a tough anodised black sandblasted finish with silver decals to match the hub. ### Enduro ABEC 5 Bearings: After extensive testing with various brands of bearings, Nukeproof chose to use Enduro ABEC 5 bearings in this front wheel. These bearings have the “LLU/LLB” seal type, which uses two lips that make light contact in a groove to create a labyrinth where the water or dirt has a more difficult time to penetrate. LLU seals are similar, only the contact pressure or interference fit is greater to improve the seal. Enduro bearings have 80% grease fill on both sides This delivers full coverage, removing any dry pockets and avoiding metal on metal contact or wear. Note. The axle may feel tight when new, but will free up after when ridden. ### What's Included In The Box?: All wheels are sold individually, allowing riders to pick wheels to suit their frame set up. Horizon PRO wheels come pre-taped with a silver Nukeproof Horizon tubeless valve installed. All riders need to do is fit a tyre of choice and add sealant. The tubeless valve supplied with a Nukeproof Horizon Tubeless valve which is compatible with Nukeproof ARD (and other rim protection/ inserts brands). A full range of spare parts, hub, freehub conversions kits, spokes, rims and maintenance tools are available.
